TL;DR
- Efforts like Graphene OS face increasing pressure from apps that refuse to run on non-standard Android.
- The custom ROM project characterizes Google’s approach to device attestation as incomplete and flawed.
- Graphene OS is prepared to take legal action if Google won’t let it pass Play Integrity checks.
Is has been discussed, I read once here: https://discuss.grapheneos.org/d/475-wallet-google-pay/2 about it, but sadly the tweet is gone and I dont remeber the exact reason.
